Description

The present invention relates to architectural equipment layout design support system.

  Conventionally, equipment related to air conditioning and sanitary facilities of buildings has been arranged in a dedicated machine room or a rooftop dedicated space provided inside the building. Air-conditioning / sanitary equipment here refers to air-conditioning equipment that controls the temperature and humidity of air, water supply and drainage equipment such as drinking water and drainage, or fuel supply equipment related to fuel supply such as oil and gas.

  For example, when equipment and piping related to air conditioning and sanitary facilities are placed in a machine room, the conventional method uses a subcontractor (hereinafter referred to as subcontractor), which is a specialized contractor who subcontracts equipment construction from a general contractor (hereinafter referred to as general contractor). Was ordered from equipment manufacturers, and almost 100% on-site construction was performed by subcontractor plumbers. In addition, in the unitized construction method, piping around the pump and pipe shafts, etc., is assembled to some extent in advance and then transported to the site and installed. In the machine room full unit construction method, a refrigerator or boiler is used. Assembling methods such as heat sources such as pumps, transport equipment such as pumps, headers and water tanks, cans such as cushion tanks for pressure relief and piping etc. are assembled at the factory, divided into parts, transported to the site, and recombined Was done.

  Among the above three methods, the machine room full unit method has a large degree of freedom in the process, has a large environmental management effect, can reduce the material used (pipe weight), has a small occupied volume, and has a construction period on site. On the other hand, there is a lot of merit that it can be shortened, but since high planning power is required, if there is no experienced engineer with specialized knowledge, the disadvantage becomes larger.

  As a design procedure for equipment in a conventional machine room, the planning of the entire building, the basic design, and the implementation design were performed in this order. First, at the planning / basic design stage, (1) an architectural design designer generally designs a large frame such as a building size, structure, assumed use, layout of each room, building material, and the like. (2) The designer of air conditioning equipment and sanitary equipment (hereinafter collectively referred to as equipment designer) calculates the air conditioning load based on the planned design and basic design of the architectural design, and selects the optimum air conditioning system. At this point, it can be assumed whether there is a machine room and the equipment to be placed in that machine room, and the facility designer considers the approximate size of the machine room based on past experience and experience. The size of the equipment may be checked, but at this stage it is common not to go into the individual equipment and do a rigorous dimensional survey.) (3) Architectural design designers and equipment designers negotiate, determine the size and position of the machine room, and modify the basic design.

  Subsequently, at the stage of the implementation design, (1) the architectural design designer determines the details of the specifications such as the outer wall and partition of the building based on the basic design described above, and determines the layout and usage of each room. (2) The facility designer calculates the air-conditioning hygiene load (hereinafter referred to as air-conditioning load) and selects an air-conditioning hygiene device (hereinafter referred to as air-conditioning device) suitable for each room. (3) Heat source equipment (refrigerators, boilers, heat exchangers, cooling towers, etc.), transport equipment (pumps), cans (tanks, headers), piping / accessory equipment ( (Piping, fittings, valves, control equipment) are selected, and the arrangement of equipment and piping is determined. (4) Create equipment tables and system diagrams, determine the equipment layout in the machine room, and enter the piping and ducts that connect them.

  In this way, the person in charge of building facility design is mainly responsible for designing the thermal load and system of the entire building, and the design of the machine room is that part, and the arrangement of equipment and piping to be placed in the machine room The decision is even more part. In addition, in the construction equipment industry, the consciousness of drawing drawings for estimation remains a common practice, and the layout shown in the drawing is not always realized completely. is there.

  For this reason, in general, regarding the selection and arrangement of equipment in the machine room, the contractor who undertakes the selection selects equipment that meets the conditions of the design drawing, creates a design drawing called the construction drawing, and submits it to the designer. To do. The designer gives correction instructions and approvals while confirming this construction drawing. The contractor confirms the construction drawings finally approved, and gives correction instructions and approvals. And the construction contractor is performing construction based on the construction drawing finally approved.

  In addition, inventions related to air conditioning equipment include those that make it possible to easily and quickly estimate the cost of air conditioning equipment, and to easily change the design by changing the coefficients necessary for the design of the air conditioning equipment (patents) Reference 1).

  Furthermore, as an invention related to a building design system, it is not necessary to re-enter the equipment data input when designing the structural frame using the architectural CAD, when designing the equipment using the equipment CAD. There was a thing (patent document 2).

JP 2002-115886 A JP-A-6-203110

  However, in such background technology, as a conventional practice in the building equipment industry, the designer does not create a drawing that is responsible for the model number and arrangement of equipment at the time of design. In many cases, it is not necessary to have the ability to create a drawing that guarantees this, so there are not a few designers who do not have the ability to determine detailed specifications and arrangement of equipment and piping.

  As a result, the creation of the construction drawing including the equipment arrangement in the machine room is generally after the application for confirmation of the design drawing and after the start of construction determined by the facility contractor. In some cases, it is done after the construction of the building frame is completed, so even if the size of the machine room is different from the size and height required for the actual equipment installation, the size of the machine room should be reduced. It is impossible to optimize later. If the machine room is larger than necessary, building assets will be lost, and conversely, if the machine room is small, it is necessary to align the equipment layout with the machine room. There was a problem that the construction cost was higher than the estimated amount because it was going to be handled by the handling of the piping.

  In addition, buildings are generally said to be produced as a single product, and the design of each building is different. Therefore, the arrangement of equipment inside the machine room will take several days for the person in charge of construction to meet the building conditions. Designed for each product. In that case, it is completed according to the designer's ability (design experience for air conditioning and sanitary equipment, product knowledge amount for equipment, ability to select optimal equipment according to building conditions, equipment placement ability, piping handling ability) There is a problem that the result (space efficiency, cost, securing of a work flow line for maintenance, etc.) is greatly affected. For this reason, the point was how to handle an experienced and capable designer.

  However, even if an experienced designer is in charge, design and approval procedures are exchanged between the designer and the contractor when designing with the conventional building equipment design procedure, the time and In addition to the time and effort, each time the design contents are changed or supplemented, a huge amount of time and effort are added.

The present invention has been made in view of the above, and it is possible to easily create a device layout design drawing that can be constructed even by a general-purpose facility designer in a short period of time, and to create the created device layout design drawing. by using, it is possible to optimize the size of the machine room at the design stage of the building design designer, to eliminate the surplus space of the machine room, wasteful construction costs required to architectural equipment layout design you a The first object is to provide a support system.

In addition, the design of the equipment layout drawing by the contractor is unnecessary, reducing the drawing production cost, reducing the items to be confirmed between the designer and the contractor, improving the work efficiency of both, and facilitating the correspondence to the short-term property, by increasing the estimate accuracy, to provide a architectural equipment layout design support system which can improve the transparency of construction estimates and construction contract with the second object.

Knowing the size and shape of the equipment, you can calculate the optimal layout by referring to pipe connection information, pipe route information, or pipe shape information, etc. 3D model can be easily obtained, and an equipment layout design drawing and the like that can be constructed can be created based on this. This is different from the conventional design order in which devices are arranged so as to fit the existing arrangement space, and by calculating the three-dimensional model with the most space efficiency and short piping distance without considering the arrangement space. The design period can be shortened, the material cost and the construction cost can be reduced, and an equipment layout design drawing that can be constructed can be created based on this.

In addition, the architectural equipment arrangement design support method according to the present invention automatically arranges headers on the selected system when selecting a system system diagram for connecting the heat source equipment and the transport equipment from the basic pattern of the database.

In addition, the building equipment arrangement design support method according to the present invention is adapted to the equipment arrangement space based on the calculated three-dimensional model when the equipment arrangement space of the air conditioning / sanitary equipment of the building is determined in advance. As the 3D model is partially modified as described above, the most space efficient and short piping distance is premised on the 3D model. Since only the minimum corrections are made, it is possible to adapt the air-conditioning / sanitary equipment to the equipment placement space without taking time and effort while maintaining the space efficiency and the short piping distance as much as possible. .

In addition, the building equipment device layout design support method according to the present invention is a device, system system diagram, door, buffer space, selection contents such as the direction of the three-dimensional block, or whenever input information is changed, Since the 3D model is recalculated, a 3D model is created sequentially according to the selection contents of the devices and the change of input information, and these can be compared and compared. There is an effect that design support becomes possible.

The shape and the like can be grasped, and further, by referring to the piping connection information, piping route information, or piping shape information in the database, the space efficiency is good and the material cost and the construction cost can be reduced. A three-dimensional model can be easily obtained, and can be converted into a design book and a construction management document corresponding to each operator based on the three-dimensional model. In particular, because it is possible to create a concrete equipment layout plan that can be constructed with the ability to meet the requirements of the building at the designer's stage in a short period of time, it can also be reflected in the design of the building, There is no loss in the space in the machine room, and construction costs and material costs can be saved accordingly.

In addition, the building equipment arrangement design support system according to the present invention is for identifying each operator when there is an application for use of the system with the project name and the user name from the operator to the design support service entity. Since the design support service entity issues an identification symbol and sets the user table for managing it, the identification name can be used to accurately identify the project name and each operator, depending on the operator. Even when data that has been changed or processed is provided, or even when a plurality of cases are processed simultaneously in parallel, there is an effect that a mistake in case processing can be prevented.

In the building equipment arrangement design support system according to the present invention , the design support service entity classifies users for each project and sets an authority table for managing access authority to information. Viewing authority and modification / change authority can be set according to the situation, and unauthorized access from outsiders can be eliminated.

In addition, the building equipment arrangement design support system according to the present invention performs a recalculation every time an operator with modification authority changes a design specification content that has already been input by the three-dimensional model creation unit. A new 3D model is created, and each new 3D model and the original 3D model are related to each other and stored in the database. Therefore, every time the operator changes the design specification content that has already been input. Since a 3D model based on the new input content is created and can be compared with the original 3D model, it is immediately known how the design specification content will be changed and what the design result will be. However, it can be easily returned to the original state, and the design specification contents can be determined while simulating.

The building equipment arrangement design support system according to the present invention calculates at least one of the weight of the piping and the construction cost by the three-dimensional model creation unit based on the information input by the operator, and converts the calculation result into data conversion Since it is processed in the processing unit and displayed on the information terminal on the operator side, the operator can easily perform a simulation for inputting information and correcting information while looking at the calculation results of the weight of the piping and the construction cost. .

  Embodiments of a building equipment arrangement arrangement support method and a building equipment arrangement arrangement support system according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  FIG. 1 is a flowchart for explaining a construction facility equipment layout design support method of the present invention. As shown in FIG. 1, the first feature of the construction equipment arrangement arrangement support method of the present invention is that a database is first created about basic design information of equipment used for air conditioning and sanitary equipment of buildings. (See step S1). By creating this data base in advance, in addition to the equipment number, specifications, size, shape, control method, pipe connection information of equipment used for building air conditioning and sanitary facilities, system system diagram and pipe route information, or Information necessary for designing such as piping shape information can be easily obtained by simply inquiring the database. This means that even if the operator does not have special knowledge or ability, it is necessary to input necessary information while interacting with the database, and then select from narrowed down devices based on the input information. Therefore, it is possible to specifically determine appropriate devices (see Steps S2 to S6), which means that a three-dimensional model using these devices can be created. In step S4, an example of device arrangement using a header has been described. However, a device configuration that does not use a header may of course be used.

  The second feature of the building equipment arrangement design support method is that the volume of the entire equipment is the smallest and the piping distance is the shortest, without taking the equipment arrangement space into consideration when creating the three-dimensional model. It is in the point which calculates as follows (refer step S8). In the past, the machine room for placing equipment was determined in advance, and considering the equipment, piping route, etc. considering its shape, volume, door position, piping position, etc. The space efficiency and construction cost were greatly influenced by the ability and the years of experience at the time of creation. However, in the present invention, a designer (design office, general contractor, sub-contractor, combination member) is provided in order to provide design support for automatically designing a three-dimensional model that provides the best space efficiency without considering the device layout space. Any operator in the production factory) will not be affected by the ability and years of experience.

  Then, the calculation is performed in step S8, and a three-dimensional model is created. However, when the input information is corrected by an operator having correction authority, the process returns to step S8 in step S9 and recalculates each time. And a three-dimensional model with the corrected content is created. The corrected three-dimensional model is stored in a file different from the original three-dimensional model, correlated with each other, and stored in a database or the like. For this reason, there is an advantage that it is easy to know what information should be input by comparing the three-dimensional models according to the correction contents.

  Furthermore, the third feature of this construction equipment arrangement design support method is that if the created 3D model does not fit in the actual installation space, only the parts that do not fit are partially corrected, and space efficient design is achieved. The point is to leave as much as possible (see step S10). For this reason, there is an advantage that even if there is a design change, it can be easily performed in a short time, and the basic space efficiency and the short piping distance can be maintained as much as possible.

  As shown in FIG. 1, the building facility equipment layout design support method creates a database on basic design information of equipment used for air conditioning / sanitary equipment for buildings (step S1), and performs air conditioning while interacting with the database. A specific heat source device is selected by inputting at least one of the type, device number, number, specification, and control method of the heat source device used in the sanitary facility (step S2). Further, at least one of the usage, device number, number, specification, and control method of the transfer device used for the air conditioning / sanitary facilities is input while interacting with the database, and a specific transfer device is selected (step S3).

  Subsequently, the system system pattern for connecting the selected heat source device and the transport device is selected from the basic patterns stored in the database, and the heat source and the transport device are arranged in each block in the selected pattern. Further, the header is automatically arranged on the system pattern (step S4). Then, it is determined whether or not tanks are used for the air conditioning / sanitary equipment (step S5), and when used, at least one of tank usage, piping system, equipment number, number of units, specifications, and control method is stored in the database A specific tank is selected (step S6).

  When the tank is not used in step S5, or after the tank is selected in step S6, the specific equipment and equipment units selected so far are inquired of the database, and a matching three-dimensional block is taken out. One or more doors for loading / unloading and maintenance are assumed on the outer periphery of the block, and a buffer space for loading / unloading and maintenance from the door is assumed (step S7).

  Subsequently, referring to the pipe connection information, pipe route information, and pipe shape information of each three-dimensional block by the database, the direction of the devices arranged in each three-dimensional block is rotated, or a buffer space for maintenance is provided. By securing the pipe connection while ensuring, the three-dimensional model is calculated and created so that the overall volume of the air conditioning / sanitary equipment is minimum and the pipe distance is the shortest (step S8). If the machine room of the building can be designed according to the created three-dimensional model, it is not necessary to change the design of the created air conditioning / sanitary equipment, and the air conditioning / sanitary equipment with the best space efficiency can be designed.

  When the input information is further corrected after calculating and creating the three-dimensional model in step S9, the process returns to step S8 to perform recalculation, and new three-dimensional models are created for the number of times of correction.

  In step S9, if the input information is not corrected or does not need to be corrected, the process proceeds to step S10. If the equipment placement space for air conditioning / sanitary facilities has already been determined, and the created 3D model fits within this equipment placement space, it is possible to achieve air conditioning / Sanitary equipment can be arranged. However, if the size, shape, pipe connection position, or the like does not match the device arrangement space, the calculated three-dimensional model is partially modified (step S9).

  As described above, according to the building equipment arrangement planning support method of the first embodiment, equipment arrangement drawings that can be constructed can be created in a short period of time even if the person in charge of equipment design has a general ability. In order to support, the size of the machine room can be optimized at the time of building design by the architectural design designer, and the excess space in the machine room can be eliminated, so that unnecessary construction costs are not required.

  Moreover, according to the construction equipment arrangement | positioning design support method of Example 1, since the design of the equipment layout drawing by a contractor becomes unnecessary, the production cost of drawing falls and the confirmation matter between a designer and a contractor reduces. Therefore, the business efficiency of both parties is improved, it is possible to deal with short-term construction properties, and the estimation accuracy is improved, so that the transparency of the construction estimate and the construction contract can be improved.

  Furthermore, according to the building equipment arrangement design support method of the first embodiment, when the input information related to the design specification is corrected after the 3D model is created, recalculation is performed each time, and a new 3D model is created. Since the design result corresponding to the input information can be confirmed on the spot, the input information can be selected on the contrary while viewing the design result.

  FIG. 2 is a system configuration diagram for explaining the outline of the building facility equipment arrangement design support system according to the second embodiment of the present invention. The building equipment arrangement design support system shown in FIG. 2 is mainly used in an air conditioning heat source system arranged in a building equipment machine room or an area called a machine yard (hereinafter referred to as a machine room). The main target is equipment systems that make heavy use of piping such as hot water supply systems.

  This building equipment arrangement design support system mainly supports equipment arrangement related to air conditioning and sanitary equipment in machine rooms of buildings and the size, specifications, and arrangement of piping that connects them. It is constructed by a computer system via a network.

  In this building equipment arrangement design support system, first, the operator of the design office 13 determines the type and number of equipment to be arranged inside the machine room, the capacity, the performance value to be requested, etc. In this way, the three-dimensional model when the equipment is assembled in the design support service main body 10 and basic data relating to the equipment are created.

  FIG. 3 is a block diagram illustrating a configuration example of the design support service entity of FIG. As shown in FIG. 3, the design support service entity 10 includes a server 10a, a control unit 10b, a database 10c, a three-dimensional CAD 10d as a three-dimensional model creation unit, a data conversion processing unit 10e, and the like. When the operator of the design office 13 shown in FIG. 2 accesses the server 10a of the design support service main body 10 via the Internet 11, the control unit 10b uses the air conditioning / sanitary equipment stored in the database 10c in advance. A screen for inputting necessary data interactively is presented to the operator based on the basic design basic information. The operator can specify information necessary for creating a three-dimensional model simply by inputting specific capability conditions and device information while viewing the input screen. The database 10c of the design support service entity 10 stores detailed device information, narrows down the types of devices according to required capabilities and requirements, and checks whether the combination of devices is appropriate. Even if the operator of the design office 13 does not have the specific equipment information necessary for input, the operator can select from the choices displayed by opening the combo box, or display a warning screen during input. As a result, it is possible to input a suitable information, and to support design of a three-dimensional model that is a basis for creating a feasible device layout and the like.

  The three-dimensional CAD 10d in the design support service entity 10 in FIG. 3 performs a calculation process for creating a three-dimensional model based on information interactively input with the design office 13 described above. . The three-dimensional CAD 10d can obtain its shape and size, pipe connection information, and the like by inquiring the database 10c for the input specific device information. For this reason, by handling it as a three-dimensional block, it is necessary as a positional relationship between the required number of devices and other devices, piping route, number of doors for loading / unloading, position, size, and work flow line for maintenance. In consideration of all buffer spaces, a three-dimensional model is calculated that minimizes the overall volume and minimizes the piping distance while changing the orientation and position of the devices arranged in each three-dimensional block. In addition, the three-dimensional CAD 10d can also calculate the weight of the piping, the construction cost, and the like based on information input by the operator.

  The data conversion processing unit 10e in the design support service main body 10 of FIG. 3 is based on the three-dimensional model created by the three-dimensional CAD 10c and basic information, and the building owner 12, the design office 13, the general contractor 14, and the subcontractor 15 Data conversion and processing according to the combination member manufacturing factory 16 and the member trading company 17 are performed. Regarding the identification of each operator, when using the system, if there is a use application with a case name and a user name from the operator, an identification symbol (user ID, password, etc.) is given from the design support service entity 10. This is done by setting a user table in the database 10c for issuing and managing it. Then, for example, a system diagram, equipment layout diagram, design calculation document, automatic control specification, etc. are created and sent to the design office 13, and a system diagram and equipment layout are sent to the general contractor 14 and sub-contractor 15. Create and send drawings, design calculation sheets, automatic control specifications, and drawings, unit three-side views, used material list, estimate sheet, used equipment list, etc. Specifications, detailed production drawings, used device list, used material list, etc. are created and sent, and to the member trading company 17, property information, used device list, used material list, etc. are created and sent. The data conversion processing unit 10e processes the calculation results such as the weight of pipes and the construction amount calculated by the three-dimensional CAD 10d on the screen of each operator's information terminal, and always displays these information. May be. Thus, the operator can input information and correct information while observing the calculation results of the weights of pipes and the construction amount that are always displayed, and can easily perform a simulation. It should be noted that the calculation results relating to the weights of pipes, construction costs, etc. that are always displayed on the screen are recalculated every time the input information is changed, and it is necessary to always display the latest calculation results.

  Furthermore, since this building equipment arrangement arrangement design support system is connected to the design support service main body 10 and the information terminal of each operator via the Internet 11, it can be processed remotely using the Internet, Of course, a configuration in which a plurality of computers cooperate to perform distributed processing is also possible.

  Next, the operation of the second embodiment will be described. First, as shown in FIG. 2, the users who use this system (the building owner 12, the design office 13, the general contractor 14, the subcontractor 15, the combination member manufacturing factory 16, the member trading company 17, etc.) are system operators. A system support application is made to the design support service entity 10 along with the project name and user name via the Internet 11. Then, the design support service entity 10 issues a pair of identification symbols (user ID and password) to the applicant, sets a table for managing it (hereinafter referred to as a user table), and sets each construction project. Item ID is set in.

  In the above-described user table, a major classification is registered for each user ID, and one of the users belonging to each major classification is classified as a “responsible person” of a minor classification. Then, the user classified as “responsible person” sets “responsible agent” and “person in charge” as subclasses of other users belonging to the same major class. FIG. 4 is a diagram illustrating an example in which a large classification and a small classification are created for each user.

  The design support service entity 10 creates a table (hereinafter referred to as an authority table) for managing user classification and information access authority for each construction project (see FIG. 26 described later). FIG. 5 is a diagram showing the input (write and delete) authority and the viewing authority in the user table and the authority table described above. In FIG. 5, the input authority is indicated by ◎ and the viewing authority is indicated by ◯.

  Then, the design support service entity 10 of the system operator permits the use of the system by confirming the match between the user ID and password of each operator using the user table. In this system, the access authority for user data is limited by the user ID of the operator and the authority table. This is because the authority of input is different for data shared by users, and it is necessary to prevent unauthorized persons from changing data without permission.

  In addition to the authority based on the previous user classification, the system operator can also grant the input of the case information to a specific user and permit the input of the case information. FIG. 6 is a diagram illustrating an example of a case table that grants input authority of case information to a specific user. As shown in FIG. 6, a specific user who is permitted to input in the project table can input a construction name, a construction location, a project name, a deadline related to the design process, and information related to the construction work period. Further, the user can input information with predetermined authority for information that is not predetermined with authority. The project in FIG. 6 is handled as a separate project for each machine room (construction area) even in the same construction. This is because the construction contents are different for each area. Also in the case of FIG. 6, the input authority is indicated by ◎ and the browsing authority is indicated by ◯.

Furthermore, if there is an instruction to draw a system diagram and information input necessary for the drawing has been performed, the control unit 10b of the design support service entity 10 uses the three-dimensional CAD 10d based on the input information in FIG. A system diagram 220 as shown is automatically drawn and displayed.

(Design support system: layout)
Next, when there is a drawing instruction for the layout drawing, the design support service entity 10 performs the calculation based on the information input on the input screen, so that the three-dimensional CAD 10d performs the calculation, thereby reducing the overall volume. A three-dimensional model having the shortest distance is drawn, and an instruction is given to draw a layout drawing based on the three-dimensional model. Here, although the above-described system diagram and the layout diagram are different from each other, in the second embodiment, when the equipment used for the air-conditioning / sanitary equipment is selected and the conditions necessary for the design are input. Based on the input information, the control unit 10b of the design support service main body 10 uses the three-dimensional CAD 10d to calculate a three-dimensional model that minimizes the overall volume of the air conditioning / sanitary equipment and minimizes the piping distance. To do. In addition, in order to make it easy to input information using the above system diagram, prior to the creation of the 3D model, input the information necessary for creating the system diagram and create a system diagram separately from the 3D model. Make it. As a premise for inputting information, when a system diagram is not necessarily required, a three-dimensional model may be created first, and a system diagram may be constructed from information necessary for creating the three-dimensional model. Such data conversion and processing is performed by the data conversion processing unit 10 e of the design support service entity 10.
Hereinafter, a procedure for creating a layout diagram will be described in the order of (A) to (N).

  First, as a procedure for creating a layout diagram (three-dimensional model), (A) the operator inquires the number and type of heat sources input to the design condition database by the control unit 10b of the design support service entity 10 and uses it as a key. , Select the matching block diagram. The selected block has a plurality of blocks to which a unit should be assigned for each role of the device. This block is a three-dimensional block that represents the size and shape of the equipment.

  At least one door for loading / unloading and maintenance is assumed on the outer peripheral portion of the three-dimensional block, and a minimum passage (buffer space) that allows workers to reach each block from the door can be provided. To. In addition, a device to be arranged or a device unit in combination with the device is associated with at least one door in order to determine whether it can be loaded and unloaded.

  In addition, it is assumed that a replaceable device or device unit can be carried out to the outer peripheral portion and has a minimum carry-in passage (buffer space) that can be carried from the outer peripheral portion.

  Furthermore, the direction of the assigned device is assumed in advance for each three-dimensional block. Each three-dimensional block has pipe connection information of the device and pipe route information connected in advance. The piping route information described above includes contact information with the outside when the designated device is connected with the outside. Further, the pipe connection information described above refers to the position of the connection point inside the block and the type of the connection partner. Furthermore, the above-described buffer space is a work space necessary for carrying in / out or for maintenance, and becomes larger than the space when the blocks are connected by piping. However, if a double floor is installed, equipment is placed on it, and piping is placed under the double floor, the buffer space can be made smaller than in the previous case. .

  Further, the operator can rotate the orientation of the device arranged in each block by 90 degrees (in four directions) on the horizontal plane according to the procedure described later. Further, a plurality of block diagrams are prepared in the database 10c for each heat source number, type, contact information with the outside, and the like.

  FIG. 23 is a layout diagram illustrating a state in which the selected air conditioning / sanitary equipment is disposed in the machine room, and FIG. 24 is a layout illustrating a state in which piping is connected between the devices based on the device layout in FIG. FIG. 25 is a layout diagram in the case where the same air-conditioning / sanitary equipment as in FIG. 24 is disposed in differently shaped machine rooms. As shown in FIG. 23, five doors 231, 232, 233, 234, and 235 are assumed here for the machine room 230, and the cold / hot water secondary pump unit 236 is carried out from each door (in / out from the direction of arrow a). , A cold / hot water primary pump unit 237 and a header 239 (in / out from the direction of arrow b), a cooling water pump unit 238 (in / out from the direction of arrow c), and two gas-fired cold / hot water generators 240 and 241 (indicated by arrows d) The equipment is arranged assuming the state of carrying in and out from the direction e and e). In addition, the alternate long and short dash line surrounding each block in FIG. 23 indicates a buffer space (also referred to as a service space here) for loading / unloading of equipment and maintenance, in which other blocks The devices are arranged so that the walls of the devices and the machine room 230 do not enter. However, the service spaces can be arranged so as to overlap if there is a sharable relationship (FIGS. 23 to 25 show an example in which a part of the space is shared). Furthermore, the broken line portions extending from the gas-fired cold / hot water generators 240 and 241 in FIG. 23 indicate the tube drawing space during maintenance. The tube drawing space need not always be secured, but may be any space that can be secured during maintenance. In the example of FIG. 23, a space can be secured by opening the door 234 and the door 235 during maintenance.

  (B) The database 10c is prepared assuming the main block diagram required by the operator, but if there is no corresponding one, an error message is sent to the operator and the system operator of the design support service entity 10 itself. To return. This error message includes a notification of a time set in advance by the system operator as a time during which the system operator can mount the block diagram. Thereafter, the system operator creates and adds the block diagram separately. When the additional work is completed, the design support service entity 10 automatically distributes an e-mail to the effect that the operation is possible to the operator.

  (C) Next, the operation will be described with reference to the block diagrams of FIGS. The specifications of the gas-fired cold / hot water generators 240 and 241, the cold / hot water primary pump unit 237, the cooling water pump unit 238, the header 239, and the cold / hot water secondary pump unit 236 are read from the design condition database, and the corresponding figure is stored in the database 10 c. Choose from.

  The corresponding figure has the following characteristics. That is, the external shape of a model that exists and can be used is accurately represented in a graphic form, but there are some units that express the external shape of the unit, such as the pump units 236 to 238 described above. If the position of the pipe connection information in the block diagram does not match the connection position of the single device, pipes up to the position of the pipe connection information in the block diagram are included. In addition, the figure has piping information up to the position of the pipe connection information so that the route information of the block diagram is not affected even if the orientation is changed. In this case, there are four ways at the maximum, and the size of the figure may change depending on the direction of the figure. Furthermore, it also has information on the diameter of the pipe to be connected. In addition, the space required for equipment maintenance, such as a part drawing space for exchanging internal parts (for example, a tube drawing space), is shown in a different expression from the outer shape, and in FIGS. is doing. In addition, the work space of the worker performing maintenance is also expressed by a one-dot chain line in FIG. 23 and FIG. 24 by opening a certain space around the equipment. Further, in the case where the devices can be carried in divided, the outline of the minimum unit is represented in a graphic form.

  (D) The graphic selected in this way is arranged in the assumed direction in the block shown in the block diagram of FIG.

  (E) The three-dimensional CAD 10d of the design support service main body 10 transforms the size of each block in the block diagram into the size of the arranged figure so that the space necessary for maintenance (so-called work space) fits in the buffer space. Widen the buffer space. In the case of FIG. 23, since the block which assumed the buffer space required with respect to an apparatus is previously arrange | positioned, it is not necessary to expand buffer space any more.

  Subsequently, the three-dimensional CAD 10d of the design support service main body 10 calculates the door size into which the arranged equipment can be carried in, and is held in the database by the piping diameter information of the arranged figure, the piping route information of the block diagram, and the database. The automatic operation diagram is performed using the piping material information, and the buffer space is expanded to such a size that the piping material can be arranged. The design support service entity 10 calculates the area of the expanded block diagram and creates the arranged equipment list and the piping material list. FIG. 24 is a diagram illustrating a state in which pipes connecting the respective blocks in FIG. 23 are appropriately arranged. In the case of FIG. 24, piping can be performed in a predetermined piping path using piping material required in the service space assumed for each block, so there is no need to widen the buffer space during piping.

  Furthermore, the design support service entity 10 calculates a design price using a device list, a piping material list, a preset unit price list, and a work amount (work cost) table. However, since the data conversion processing unit 10e can prepare a plurality of unit price tables, work amount tables, etc. for each operator, the design support service entity 10 determines the operator and selects the optimal one according to the operator. Use it.

  (F) The design support service entity 10 ends the drawing calculation, displays a layout diagram as shown in FIG. 24 on the screen of the operator, and displays a displayable result according to the authority of the operator. Like that. FIG. 26 is a diagram showing an example of setting of an authority table in which which person in charge has browsing authority and correction authority for each content, and a circle in the figure indicates data browsing authority and an annotation column. Indicates that the user has the authority to add data, and the mark ● indicates that the user has authority to view and modify data.

  (G) Then, when the layout is determined, the post-processing method is selected. In other words, the design support service entity 10 makes an inquiry about post-processing such as storage and printing to the operator, assigns an ID number for specifying the data to be issued, and executes the post-processing selected by the operator To do.

  (H) When correcting the layout drawing or correcting the orientation of the device, select “device orientation” in the correction menu and select the device to be corrected. Accordingly, the design support service entity 10 performs the above-described processes (D) to (G) again using the figure in which the orientation of the device is corrected. The machine room 250 shown in FIG. 25 is a room that is longer in the vertical direction (up and down direction in the figure) and shorter in the horizontal direction (left and right direction in the figure) than the machine room 230 in FIGS. Near the center of the machine room 250, there are protrusions of columns 253 and 254, and the number of doors is only 251 and 252 compared to the five in FIGS. 23 and 24, and all equipment can be carried in and out of these two doors. It is in a situation that must be done.

  (I) Therefore, when the operator corrects the position of the door by correcting the layout drawing, the user selects “move door” from the correction menu and selects the door to be moved. As a result, the design support service entity 10 sets a range of door positions that can be moved by adding an alternative passage (a buffer space that is increased by expanding the outer buffer portion or the internal buffer space) registered in the block diagram in advance. The above processes (D) to (H) are performed again. For example, in the case of FIG. 25, it can be considered that the doors of FIG. 23 and FIG. 24 are moved and combined into two.

  (J) When deleting one of the plurality of doors by correcting the layout drawing, select “Delete Door” from the correction menu and select the door to be deleted. As a result, the design support service entity 10 deletes the door and adds an alternative passage previously registered in the block diagram. In the case of FIG. 25, three doors 232, 233, and 234 are deleted from the doors of FIGS. 23 and 24, and the doors 251 and 252 of FIG. 25 corresponding to the doors 231 and 235 are left. In this case, the unique carry-in / out port of the cold / hot water primary pump unit 237, the header 239, the cooling water pump unit 238, and the gas-fired cold / hot water generator 240 is deleted. For this reason, as for the alternative passages of the cold / hot water primary pump unit 237, the header 239, and the cooling water pump unit 238, a passage that can be carried in and out through the arrows f, h, i, j using the door 251 is secured. ing. Moreover, about the alternative channel | path of the gas-fired cold / hot water generator 240, the channel | path which can be carried in / out through the arrow k, l, m using the door 252 is ensured.

  (K) In addition, when changing the connection point with the outside of the machine room area by correcting the layout drawing, the operator selects “connection point with the outside” from the correction menu. As a result, the design support service entity 10 displays a system name having a connection point with the outside. When the operator selects a system, the design support service entity 10 displays the change destination candidate points for that system.

  (L) When the operator selects the change destination, the design support service entity 10 adds the condition of the selected route information and performs the processes (A) to (K).

  (M) In addition, when the operator sets a column in the installation space by correcting the layout drawing, the user selects “Set column” in the correction menu and answers the questions from the system described below. . Thus, the design support service entity 10 can interactively present the column size, the arrangement interval, and the reference point to the operator side, and display them on the screen when their contents are determined. For example, as shown in FIG. 25, since columns 253 and 254 are arranged near the center of the machine room 250, if an operator inputs the size, arrangement interval, and reference point of the columns interactively, A column can be displayed on the screen accordingly.

  (N) When moving the equipment block by correcting the layout drawing, the operator selects “move block” from the correction menu. As a result, the design support service entity 10 displays a block list on the screen on the operator side, and requests the operator to move or fix the block. The initial value is all moved. Therefore, when the operator designates a block to be fixed, the design support service entity 10 requests to input the moving direction and distance regarding the moving block. On the other hand, when the movement direction and distance are input from the operator, the design support service entity 10 moves the movement-instructed items collectively and connects the fixed route to the moving route. To change. For the subsequent operation, the operations after (E) are performed. For example, in the case of FIG. 25, the blocks of the gas-fired cold / hot water generators 240, 241 give instructions for fixing, and the cold / hot water primary pump unit 237, the header 239, the cooling water pump unit 238, and the cold / hot water secondary pump unit 236. In this case, the device block is moved by inputting the moving direction and the distance, and the piping path connecting the fixed one and the moving one is changed.

  As described above, according to the second embodiment, by instructing drawing of a system diagram, a layout diagram, etc., a specific device is selected at the design office stage, and the layout of the device is determined. In addition to assuming a door for loading and unloading, and taking into account the loading and unloading passages and the buffer space for maintenance, the overall volume is minimal. Create a three-dimensional model with the shortest distance. Then, by extracting information necessary for the system diagram and the layout diagram from the three-dimensional model and converting / processing it, the system diagram, the layout diagram, etc. can be easily drawn in a short period of time. In the past, these drawing work was arranged from the design office via the general contractors and sub-contractors and exchanged with the contractor using the original design drawings, etc. The figure was completed. However, in the second embodiment, even if a designer with a general ability at the design office stage can do the design in a few days, it is reflected in the design stage of a building machine room or the like. It is possible to reduce the construction cost by suppressing the space loss of the machine room and the like. In addition, even if the layout drawing that was drawn does not fit into the existing space such as a machine room, it is only necessary to make partial corrections only for the parts that do not fit, thus reducing the time and cost of the correction. It can be adapted to various equipment placement spaces with little effort.

  Using the building equipment arrangement design support system described above, the drafting or created design books and construction management documents are exchanged between multiple parties, confirming, approving, changing instructions, etc. It is necessary to determine the model and create design books and construction management documents. However, in the conventional workflow system, the decision is made while exchanging the documents themselves, so that if there is a discrepancy between the documents, it is not easy to correct it. In other words, what is required in the approval work for building work is to approve whether the model to be expressed is appropriate, not to approve the document itself. In addition, the degree of detail required for each document varies depending on the positions and roles of the parties involved in the exchange of drawings and other representation methods. There was a restriction that the content could not be changed according to the role. Therefore, since it is necessary to exchange documents containing information that is not necessarily required for each person concerned, it takes a lot of work and time to make document confirmation work, approval work, change instructions, etc. There were not a few possibilities.

  Therefore, in the construction management support system of the third embodiment, functions of a workflow system that supports work such as approval and storage of drawings related to a plurality of parties, and data related to design such as the automatic design system described above are provided. It also has a linkage function with a database that is stored and processed separately. Therefore, this construction management support system issues system diagrams and layout diagrams based on the three-dimensional model created by the automatic design system, and further, estimates, construction drawings, process schedules, By creating forms such as delivery equipment specifications, there are no discrepancies between documents, and these can be managed together. As described above, the construction management support system according to the third embodiment is a workflow that distributes the three-dimensional model itself, and in order to make this possible visually, in a data format necessary for each party for convenience. The format is to provide and seek approval for this. This is because the various documents are merely means for perceiving the three-dimensional model, and it is necessary to freely change the display format and accuracy of the documents to be presented in accordance with the positions and approval capabilities of the parties concerned.

  The construction management support system saves the data entered at the time of initial registration, searched data, calculated data, and output data as they are or after processing them into a 3D model or the required format, and reworking them as necessary. Output. These data are correlated with each other so that the data can be traced when re-correction is performed. This construction management support system includes the name of the building owner, the name of the planned construction contractor, the name of the construction decision trader, etc., design data (design drawings, calculation sheets, other requested items), various government agency approval and approval documents, and construction approval request information (approval) Requested construction drawings, approval requested delivery equipment specifications, etc.), construction approval information (approved construction drawings, approved delivery equipment specifications, etc.), design change requests, design change instructions, etc. can be shared via the Internet 11 I am doing so.

  Then, the data related to the approval work of the construction management support system, including the three-dimensional model, is created and stored separately, not overwritten. This construction management support system controls the disclosure and non-disclosure of approval work target information and operates as a workflow system. FIG. 27 is a diagram showing an example of setting the data handling authority and the guide mail transmission destination for each person in charge. In the figure, ○ indicates a person who has data viewing authority, and ◎ indicates data viewing authority. And the person who has the authority to add data, and ● the person who has the authority to browse and modify the data browsing authority. As shown in FIG. 27, during operation as a workflow, movement information of operation authority can be disclosed to the parties concerned by a setting different from the workflow route setting. In addition, regarding the disclosure, it can be used in combination with the transmission (destination) of an electronic mail.

  By using such a construction management support system, it is possible to list the management status and systematize document management, so it is possible to have an information management function suitable for multi-layer subcontracting structures such as the construction industry. it can.

  And this construction management support system keeps the meeting status between each contractor undisclosed, but it also communicates the information transfer status and approval schedule to the highest-ranked parties as much as possible. Can be speeded up.

  If the application for approval was rejected, the rejection of the application for approval was conventionally communicated in the form of reversing the approval route. However, the modified design for re-application is the one that submitted the production drawing or construction drawing. There was a time lag until then because there was a need to do it. However, in the case of the construction management system according to the third embodiment, since the original submitter can start the correction work at the same time as the return, the period required for the second approval application can be greatly shortened.

  Furthermore, the higher-level parties can grasp to some extent the history of the movement of the drawing information so far by the history (log) stored in the construction management support system and the e-mail sent from the construction management system. The effect is that the psychological distance between the related parties is reduced, and the entire correction work can be processed smoothly.

  Next, the operation of the third embodiment will be described. First, when starting up the construction management support system, an operator is identified by a user ID, and a security function is provided by restricting information that can be written or erased. Then, the project to be operated is specified, and the construction management support system database is operated.

  First, the operator performs operator identification (security check) and activates the construction management support system. Subsequently, the project to be operated is specified, and the database 10c of the construction management support service entity 10 is operated. Next, each operation state of the third embodiment will be described in detail by dividing it into the following (a) to (f).

  (A) In the case of outputting the design model, first, the system side which is the construction management support service entity 10 confirms the right of the operator, and displays only the format to which the operator has authority. For example, overall plan view, partial cross-sectional view, 3D model diagram, equipment list, quantity table, estimate, etc., scale, display details (design drawing level, construction drawing level, production drawing level), etc. Present the format to the operator. Then, the operator selects from the output formats displayed on the terminal screen.

  Subsequently, when the system side displays an output method (for example, screen display as shown in FIG. 26, PDF format file, DXF format file, VRML format file creation, etc.), the operator selects an arbitrary output method from among them. And download.

  FIG. 28 is a diagram illustrating the flow of information related to the approval work exchanged between the designer, the construction manager, the combination member manufacturing factory, and the design support service entity, and FIG. 29-1 is a combination member manufacturing. It is a figure explaining the procedure from the approval application of the factory to the approval of the subcon, or the denial / return, and FIG. 29-2 is the figure explaining the procedure from the approval application of the subcontainer to the confirmation request contents of the general contractor and the return. is there.

  (A) When the combination member manufacturing factory 16 or the subcontractor 15 uses the 3D model data registered by the automatic design system when confirming and correcting the design model and applying for approval as a production drawing or construction drawing. is there.

  First, as shown in FIG. 29-1, the combination member manufacturing factory 16 that is an operator accesses the construction management support service main body 10 via the Internet 11 to operate the automatic design system, and data for the combination member manufacturing factory. Is created or confirmed (1), the data is corrected, and the data is confirmed (2). When the data is confirmed, the system side separately stores the confirmed model, the corrected part, the operator, and the history (log) of the operation date and time.

  At the same time, the combination member manufacturing factory 16 applies to the construction management support service entity 10 for an approval work start request (3). That is, according to FIG. 27, data viewing, writing, and correction authority are set or changed. Then, according to FIGS. 27 and 29-1, the combination member manufacturing factory 16 notifies the sub-con 15 of an approval work start request notification by e-mail (4). As the notification contents, the approval work deadline, the subsequent approval flow, and the URL linked to the database operation screen only for the sub-con 15 are described. In addition, a guide mail indicating that there has been an approval work start request notification from the combination member manufacturing factory 16 to the subcontractor 15 is also sent to the design office 13 and the general contractor 14 (4). In this way, the construction management support service entity 10 creates and stores log data related to the application for approval, writing, and correction that has existed until then.

  (C) When the combination member manufacturing factory 16 or the sub-con 15 uses the above-described automatic design system to create a design model and submits an approval application, the operator of the combination member manufacturing factory 16 or the sub-con 15 performs the construction. A management support service entity 10 accesses the automatic design system to create and determine a three-dimensional model.

  On the side of the construction management support service main body 10, when there is an access from the combination member manufacturing factory 16, the automatic design system is activated to create a three-dimensional model, and the confirmed model, the changed part, the operator, the log of the operation date and time Store separately.

  Then, the operator (combination member manufacturing factory 16 or sub computer 15) applies for the approval of the created and confirmed three-dimensional model. Since the processing operation on the system side after the application for approval is the same as the operation in (a) above, redundant description is omitted here.

  (D) When the combination member manufacturing factory 16 or the sub-con 15 creates a design model without using the automatic design system and applies for approval, the operator of the combination member manufacturing factory 16 or the sub-con 15 itself Data is created using software that can create a 3D model and uploaded to the system.

  The construction management support service entity 10 on the system side saves the uploaded data, or further processes and stores the data in a data format suitable for the system.

  Then, the operator (combination member manufacturing factory 16 or sub computer 15) applies for approval of the uploaded data. Since the processing operation on the system side after the application for approval is the same as the operation in (a) above, redundant description is omitted here.

  (E) An operator such as the subcontractor 15, the general contractor 14, or the design office 13 who performs construction management (supervision) confirms and approves the content of the model approval request. For example, as shown in FIG. 29-2, the subcontractor 15 requests the construction management support service entity 10 to approve the general contractor 14 (1).

  In response to this, the construction management support service entity 10 notifies the subcon 15 to the general contractor 14 of an approval work start request by e-mail (2). As the notification contents, the approval work deadline, the subsequent approval flow, and the URL linked to the database operation screen only for the general contractor 14 are described. Also, the construction management support service entity 10 activates the automatic design system and presents a plan view, a cross-sectional view, a system diagram, a calculation sheet, a device list, or 3D image data as a confirmation menu, and requests approval. .

  The general contractor 14 inquires the construction management support service entity 10 about the approval request contents (including correction points and correction history), confirms if there are no corrections, and approves or reports the approval to the higher-level organization (3) .

  The construction management support service entity 10 on the system side sets or changes the data browsing, writing, and correction authority according to FIG. Then, according to FIG. 27 and FIG. 29-2, an approval application or a report application is notified by e-mail (4). The notification contents include a notification that there has been a return from the general contractor 14 to the subcontractor 15 and the combination member manufacturing factory 16, an approval work deadline and a subsequent approval flow, and the database operation screen is displayed only for the subcontractor 15 and the combination member manufacturing factory. The URL to be linked is described. It also creates and stores log data for previous approval applications, send-back instructions, additions, and corrections.

  (F) The case where an operator such as the subcontractor 15, the general contractor 14, or the design office 13 that performs construction management (supervision) confirms the approval request contents of the model and sends it back. For example, as shown in FIG. 9-2, the subcontractor 15 requests the construction management support service entity 10 to approve the general contractor 14 (1).

  In response to this, the construction management support service entity 10 notifies the subcon 15 to the general contractor 14 of an approval work start request by e-mail (2). As the notification contents, the approval work deadline, the subsequent approval flow, and the URL linked to the database operation screen only for the general contractor 14 are described. Also, the construction management support service entity 10 activates the automatic design system and presents a plan view, a cross-sectional view, a system diagram, a calculation sheet, a device list, or 3D image data as a confirmation menu, and requests approval. .

  The general contractor 14 inquires the construction management support service entity 10 about the contents of the approval request (including the correction part and correction history), and if there is a correction, adds the reason for return (inputs data to the specified part), An instruction to send back is given (3).

  The construction management support service entity 10 on the system side sets or changes the data browsing, writing, and correction authority according to FIG. Then, according to FIG. 27 and FIG. 29-2, the general contractor 14, the subcontractor 15, and the combination member manufacturing factory 16 are notified by e-mail (4). As the notification content, a URL linked to the database operation screen is described in the body of an e-mail addressed to a related person who should perform the next operation. It also creates and stores log data for previous approval applications, send-back instructions, additions, and corrections. Subsequent operations on the system side are the confirmation and correction approval application operations described in (a) above, and therefore redundant description is omitted.

  As described above, according to the third embodiment, since the document displayed in the construction management support system represents one section of the three-dimensional model, the problem that a plurality of documents related to the same model cause inconsistencies is solved. be able to. In addition, since the documents are managed for each three-dimensional model, the number of approvals can be reduced and the management can be simplified. Furthermore, since the information regarding the progress status of the approval work is shared among the parties concerned, it is possible to avoid a situation in which documents remain in some of the parties concerned, so that the approval work can be speeded up. In addition, the management status can be listed and document management can be organized.

  Furthermore, according to the third embodiment, since the person concerned can confirm the three-dimensional model in the form most familiar from that standpoint, it is possible to reduce confirmation errors. In addition, for the approval of the three-dimensional model, since the system displays a list of confirmation items or sequentially displays them interactively, an effect of preventing omission of confirmation can be expected. In addition, since all the approval work logs are recorded, it is possible to verify the location of responsibility for troubles occurring in products or construction results based on the approval work or the model after approval.
